If you're used to riding two strokes then it might seem quite different in comparison. Another thing with these bikes, at least I noticed on mine, is they are geared pretty low especially 1st & 2nd. I have a TT-R 125L, which stock has a 13/54 tooth sprocket set on it. which equates to 4.153:1 final drive ratio. I am actually planning on running one tooth up on the front sprocket which will change to 3.857:1. I've heard with this set-up you'll still have plenty of torque down low and have a little more gear on top. I'm not familiar with the smaller wheel version, which is what you have if your's is a TT-R 125 and not 125L.

Mine is a ttr125le. I got this for my son, and i seem to be riding it more them him lol. Anyway, I'm 210lbs and if i chop the throttle from high rev it dam near throws me off the bike. I've got a yfz450 and it's NO where near like that. I know from some research the flywheels on these things are like a lb heavier then what's on my yfz450. Just mainly wanted some confirmation, as i've never seen a bike with this much engine braking. Guess the good is the rear brake will never wear out.

This one actully needs a ring job, from the previous owner not running an air filter, as it has an excessive amout of blowby, and compression is on the low side but it does run. I can't complain to much, it wasn't running when i got it, and for the price I paid, and the money i've put into it, it's still 1/4 cost of buying one running.

I'll propably throw a wiesco piston in there to bump the compression up a tad, and maybe a cam.

I yanked the flywheel off last night to track down the starter problem. It's never good when i oneway bearing comes out in peices.

I still cant get over how dam heavy this flywheel is. I think it's gonna get chucked up in the lathe before going back on.
